ABT-737 has been assessed in a Phase 2 clinical trial investigating its effects on ex vivo ovarian cancer samples from patients [4-5,7].
Mechanism Of Action and Pharmacodynamic Effects Click here for help
BH3 antagonists hinder the interaction between antiapoptotic and proapoptotic Bcl-2 proteins which is dysregulated in cancers overexpressing antiapoptotic proteins [3]. Such antagonists should restore the activity of proapoptotic proteins, thereby leading to tumour cell death. They may even help overcome resistance to chemotherapy which is a common feature of Bcl-2-overexpressing cancers [1].
